An isolated 75MVA synchronous generator feeds its own load and operates initially at no-load at 3000 r.p.m., 50 Hz. A 20MW load is suddenly applied and the steam valves to the turbine start to open after 0.5 s due to the time-lag in the governor system. Calculate the frequency to which the generated voltage drops before the steam flow meets the new load. The stored energy for the machine is 4 kWs per kVA of generator capacity.
A votage pulse of amplitutde 10V begins at 5-sec and lasts for 20 msec,which is short compared with the respponse times and time constants of the system.This impulse si then passed through and integrator.
Your responsibility will be to do three ratios from the Activity Ratios. The three being: Inventory Turnover, Accounts Receivable Turnover, and Total Asset Turnover. Either by downloading the financial report from the Walt Disney website, or on the N..
A new 24-bit processor is being designed for operation in a cell phone (you can assume the word-size is 24 bits). Suppose the following memory values are being stored in memory that is organized where each location is 8-bits wide (byte addressable..
A particular communications system has 2 identical receiver stages connected in cascade, each with gain 7 dB and noise figure 4 dB. Compute the noise figure of the combination assuming the stages are impedance matched.
Design a Mealy state machinethat is a *majority vote* detector that indicates when the majorityof the last three samples received are ones. When at least 2out of the last 3 inputs received are ones, it will output a1.
(a) Find the matched-filter frequency response function H(f) for a perfectly rectangular (video) pulse of duration τ, andamplitude A. (Assume the pulse extends in time from -π/2 to+π/2). (b) Sketch (roughly) its magnitude abs {H(f)} for positive fr..
Design a half-wave rectifier as a dc power supply that delivers 0.2A and 15V peak values to a load. The ripple voltage is to be no more than 0.4V peak to peak. The rectifier is led from the voltage line (120Vrms, 60Hz) through a transformer.
Determine the EA or offset, if applicable from the addressing modes(i) Immediate, (ii) Direct, (iii) Register using BX, (iv) registerindirect using BX, (v) Register relative using BX, (vi) Basedindexed, and (vii) Based indexed relative.
